From my experience, when you hear a different sound from the exhaust
when trying to start the bike. A kind of thump, pop, thud sound. It is
the exhaust flapper valve getting stuck from carbon build up.

When my EC300 did it. The bike would start and run, with reduced
power when taking off in low gears until you got the revs up then it
would take off. After a couple min. riding it corrected it's self and
returned to normal.

Maybe not your problem, but a possible answer.

Just watched the video.. The thudd...duuuduuu? sound at the end of the video
seemed more to me like the sound you get when you open the throttle too
much when kicking it over.

I know I sure don't like to start my GG's with a tennis shoe. I make sure I a
wearing a decent boot. And I am a bit more aggressive when when I put a smooth
kick through on the arm.. Don't do a quick snap kick down or you can / will damage
the internal starting gears or brake the arm.

Also only start it in neutral. Don't try and start it in gear with the clutch lever pulled.
From my experience it putts too much drag on the motor and won't turn over fast
enough.

Another thought.. You might want to look into getting one of the newer kick start
levers. The old stock ones were rather small and hard to get a good push through on. The one in my attached picture is the steel one from a mid
1990's GG Pampera 280. Much longer. Not sure if these are still available.
I got mine on E-bay or possibly from Jim Snell at Rising Sun. He is a trials
dealer in Indiana. Should be googleable.

My 2 cents.
